Patent DE-3742192-A1 (DE)
Title: Method of manufacturing a pre-workpiece for one-part current contact nozzles with melting-off additional wire
Inventor: WOLF HARRY PROF DR SC TECHN
IPC: B23K9/12
Filed: 1987-12-12
Abstract: Method of manufacturing a pre-workpiece for one-part current contact nozzles for arc welding with melting-off additional wire. The invention relates to a method of manufacturing a pre-workpiece for one-part current contact nozzles. The essential new features of the invention consist in that the compression of the wear-proof components of a powder mix takes place simultaneously with the electrically conductive components of the powder mix in a special energy introduction. As a result of the method, by structural change, a wear-resistance is achieved in the current contact nozzle which makes possible a long life of the current contact nozzles.

Title: Gear arrangement for coupling two engines to a working machine
Inventor: SCHMIDT WOLFGANG DR ING
IPC: F16H3/72
Filed: 1987-12-21
Abstract: The invention relates to a gear arrangement for coupling two engines to a working machine, in which a dependence between torque and speed prevails. The gear arrangement consists of a planetary gear which allows the overlapping of the powers of the two engines along with a free speed ratio, but a predetermined torque ratio, and of which the input shafts are connected to the driven shafts of the two engines and of which the output shaft is connected to the drive shaft of the working machine. To drive the working machine by means of only one engine, the driven shaft of the other particular engine can be fixed against the rotation in at least one direction. So that, when the working machine is driven by means of one or both engines, these can work under optimum operating conditions, the planetary gear is connected to the drive shaft of the working machine via a characteristic-conversion gear having at least two selectively shiftable transmission ratios.

IPC: F02M61/20
Filed: 1988-02-05
Abstract: A fuel injection nozzle for an internal combustion engine comprises a valve body (13), which supports a first spring abutment (19) in contact with one end of a first spring (17). The other end of the spring touches a second spring abutment (21) adjustable in a hollow body (10). A second spring (18) lies between a third and a fourth spring abutment (23, 26), the third spring abutment (23) touching the second spring abutment (21) but being axially displaceable in relation thereto. The fourth spring abutment (26) is adjustably arranged in the hollow body and a projecting attachment (24) is adjustably fitted on the third spring abutment (23). After a predetermined displacement of the valve body against the force of the first spring, the projecting attachment comes in contact with the first spring abutment and the valve body continues to be displaced against the force of both springs. <IMAGE>
